Chapter 4 shifts from discussing saints in general to Sai Baba specifically. How is Sai described in this context as the Supreme Divinity?

After explaining the role of saints, Chapter 4 elevates Sai to the status of the Supreme Divinity. He is identified as the Inner Self and the Supreme God who brings joy to the world. The text states that He who is God is the Guru, and He is the joy-giving Shankar. Sai is described as the object of ultimate love, eternal, and non-dual, beyond all limitations of place, time, or object. As Chapter 4 illustrates, His divine nature is so profound that the four levels of speech cannot fully describe Him, leading the Vedas to resort to saying 'Not this, Not this' (Neti-Neti) to express His limitless essence.
